BellingenNSW"Air pollution accounted for 8.1 million deaths globally in 2021, becoming the second leading risk factor for death, including for children under five years. Of the total deaths, noncommunicable diseases including heart disease, stroke, diabetes, lung cancer, and chronic obstructive pulmonary disease (COPD) account for nearly 90% of the disease burden from air pollution.""In 2021, more than 700,000 deaths in children under 5 years were linked to air pollution; this represents 15% of all global deaths in children under five.'

DoomsdaysCWHow <a href="https://kolektiva.social/tags/AirPollution" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#AirPollution</a> is causing girls to get their first <a href="https://kolektiva.social/tags/periods" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#periods</a> earlierNew research shows that girls in the US are getting their first periods earlier. Exposure to toxic air is partly to blame.By David Cox, June 4, 2024"The same trend has also been noted around the world. South Korean scientists have described with some alarm how the number of girls displaying signs of precocious puberty – either breast development or <a href="https://kolektiva.social/tags/menstruation" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#menstruation</a> before the age of eight - increased 16-fold between 2008 and 2020."We're also seeing that these decreasing ages at puberty are even more pronounced in lower socioeconomic status groups, and ethnic minority groups," says Audrey Gaskins, an associate professor at Emory University in Atlanta, the US. "This has important implications for long-term health."Researchers like Gaskins are primarily concerned that beginning puberty earlier might trigger a cascade of events which have far-reaching consequences later in adulthood. Emerging data suggests that it may not only curtail the fertility window, particularly if these women then enter menopause sooner, but shorten their lives. Precocious puberty has been repeatedly associated with a higher risk of diseases ranging from breast and ovarian cancers, metabolic syndromes such as obesity and type 2 diabetes, and cardiovascular disease."By David Cox, June 4, 2024"For several decades, scientists around the world have become increasingly concerned by signs that girls are entering puberty at a much younger age compared with previous generations.From when girls experience their first period, something which scientists term the age of menarche, to commencing breast development, these seminal changes marking the onset of adolescence appear to be taking place progressively sooner."American girls today have been estimated to start menstruation up to four years earlier compared to girls living a century ago. In May, new data showed that while girls born between 1950 and 1969 typically began menstruating at 12.5 years, this decreased to an average of 11.9 years for the generation born in the early 2000s."The same trend has also been noted around the world.
